“He’s just 20 years of age, for heaven’s sake, and the kid’s got everything. He scores goals, makes goals, he can dribble, head it, he’s got an edge to him and puts his foot in… I think he’s fantastic.

“Didn’t he play for MK Dons against Manchester United when they beat them 4-0 in the League Cup? United should have signed him there and then. At least they would have gone home disappointed with the result but they would have had a future star for the club with them on the bus.”

However, the 69-year-old who managed Spurs between 2008 and 2012, leading the club to a Champions League quarter-final, believes his former club won’t entertain any offers for their starlet while they aim to win the Premier League title.

“Obviously, Tottenham don’t want to sell him – they are building a fantastic new stadium.

“If they continue to progress, they have got a squad that can win the title in the next year or two — so I’m sure he would want to be part of that.”

While Redknapp was full of praise for his former club, he did criticise the club’s decision to play their European games at Wembley stadium instead of at their home White Hart Lane, after Spurs limped out of the Champions League at the group stage.

Redknapp said: “I did warn that playing home games there in Europe would be a massive disadvantage to them.

“It’s such a different atmosphere at White Hart Lane, because the crowd’s on top of you and the noise is tremendous. When you’re at Wembley, the game is slower, there are big, open spaces and it’s just not the same.

“But if Mauricio Pochettino picks his best team, they have got a real chance in the Europa League. If they really want to win it, Spurs have got the players to do it. They would be my favourites.

“When they put out their strongest XI, I think Tottenham have the best team in the Premier League.

“I don’t think they will win the title now – although for me they are certain to finish in the top four.

“They are also going for the FA Cup, so it’s going to be a juggling act to see whether he really goes for the Europa League as well.”
